1）后端
package com.czxy.classes.controller; import com.czxy.classes.service.TbClassesService; import com.czxy.classes.service.TbTeacherService; import com.czxy.domain.TbTeacher; import com.czxy.vo.BaseResult; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.annotation.Resource; import java.util.List; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @RestController @RequestMapping("/teacher") public class TbTeacherController { @Resource private TbTeacherService tbTeacherService; /** * 查询所有 * @author 桐叔 * @email liangtong@itcast.cn * @return */ @GetMapping public BaseResult findAll() { List<TbTeacher> list = tbTeacherService.list(); return BaseResult.ok("查询成功", list); } }
2）前端
显示表单
展示所有老师

需求：如果某类型的老师已选，将除当前老师，其他该类型的老师禁用
实现：完善ClassesAdd.vue

async classesAdd() { // ajax添加 let { data:baseResult } = await this.$axios.post('/classes-service/classes', this.classes) // 处理 if(baseResult.code == 20000) { this.$message.success(baseResult.message) // 跳转列表页 this.$router.push('/classes/classesList') } else { this.$message.error(baseResult.message) } } 3.4 查询所有班级 3.4.1 后端实现 3.4.2 前端实现 3.5 修改班级 3.5.1 后端实现 3.5.2 前端实现
